Render Movie - World Position Pass?


I was wondering if it is possible to render out a World Position Pass?

I seem to be able to create a world position pass by making a post process material with a Absolute World Position node connected to the Emission Color.
I then apply this post process material into my PostProcessVolume in my scene - by apply my material in a post process render array element. From there I seem to be able to render out an image that appear to be a WPP but the image does not seem to work correctly when I import it into a compositing program.

When inspecting it in my compositing program - not all RGB values are translating correctly the full depth of the scene.

I am not sure what is causing the issue and any help would be much appreciated.

Thank you!!
